Lincoln Town Car climate control reset instructions

An electric issue is the most common cause for a Town Car’s A/C failure. When this happens, you’ll notice that the vent on the passenger side of your vehicle is blowing cold air while the air on the driver’s side is hot or vice versa.

To solve this, you’ll need to reboot your Lincoln Town Car HVAC system:

Turn off your Lincoln Town Car’s engine. Ensure that all lights and anything else that uses electricity are also off.

Open the hood

and locate the battery. The battery will be directly behind the passenger's side headlight for 2005 to 2009 models, or located in the trunk for all other model years.

With a half-inch wrench, unscrew the clamps on both the negative and positive battery terminals to disconnect the battery.

Wait a couple of minutes.

Reconnect both battery cables to their respective terminals, and close your car's hood (or trunk).

Start your Town Car and test the A/C system.

Worst case scenario: If following those steps didn’t do the trick, you’re dealing with a mechanical problem—not an electrical one.

Take your car to a mechanic

to get to the root of what's causing your A/C malfunction.

Other reasons your Lincoln Town Car A/C isn’t working

These are the top three most common causses of Lincoln Town Car A/C failure if the problem isn’t electrical:

Faulty A/C compressor clutch: The A/C compressor clutch helps convert energy from your engine and deliver power to the

A/C compressor

, which works with the condenser to cool the air. You’ll notice that your A/C system will not power on if this part is worn out.

A/C refrigerant leak:

A/C Refrigerant

is a chemical liquid that circulates throughout your engine to cool the air before it blows out of your vents. Your HVAC system venst will blow out air that is much warmer than it should be if your refrigerant is leaking.

Broken blower motor: The

blower motor

is the part of your HVAC that pushes the temperature-controlled air (heated or chilled) through your Lincoln’s dashboard vents. Poor or even no airflow from your A/C points to an issue with your blower motor.

While these are the most common, there are tons of other potential causes for Lincoln Town Car climate control failure, like:

Loose hose connection

Broken blower fan

Clogged
